Hi,

If you you want a quicker execution - you could also run the pings to separate hosts in parallel starting the jobs in background (&) and waiting for them with "wait" after that. You'll have to be more careful about the outputs in that case - e.g. redirect them to separate files.

Do you mean something like:
ping -c10 host1
ping -c10 host2
....
which will ping host1 10 times, then host2 10 times etc. (see `man ping` for details of the options).

If you have a list of hosts in a file, you could do:
for host in `cat [filename]`
do
ping -c10 $host
done

or:

while read host
do
ping -c10 $host
done << [filename]

If you only want to ping each host once, you can substitute '-c10' with '-c1' (again, see the man page).

Hope this helps
Laurence
